The display diagonal of a TV is the most common measure of screen size and is the distance from the top left to the bottom right of the visible part of a TV screen excluding any frame or border. One of the most important considerations when choosing the right screen size for your TV is the typical distance from which you will be viewing the screen.
A good rule of thumb is to multiply the display diagonal by 2.5 to determine the viewing distance. So a 40 inch TV is best viewed from 100 inches away, which is equivalent to 8.3 feet or 2.54m.
For home cinema setups and a truly immersive experience this ratio can be reduced to 1.2. This will give a screen size that fills 40 degrees of the viewer's field of vision. So if you viewing from a distance of 6ft (72 inches) you would need a TV display diagonal of 60 inches.

TVs with a bigger display diagonal allow you to make the most of HD content and are great for watching movies.
